TYPE-EJECTING DEVICE IN TYPE-CASTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 770,598, dated September 20, 1904.

Applicationfiled February 11, 1904. Serial No. 193,074.. (No model.)

To all whom it may concern.-

Be it known that we, JAo UEs MAYER and CHRISTIAN ALBRECHT, both citizens of the United States of America, residing at Berlin, in the Empire of Germany, have invented a new and useful Type-EjectingDevice in Type- Casting Machines, of which the following is a specification.

Our invention relates to a type-ejecting device for simultaneously ejecting a plurality of types from a type-mold of the kind described in our other application for United States patent, Serial No. 192,87 8, filed February 10, 1904, and to be used in atype-casting machine or a linotype casting and composing machine of any known kind.

The type-mold described in the said application is adapted for producinga plurality of types at a time, either single types for letters, characters, signs, figures, &c.,or grouped types, such as logotypes, word-types, ornament-types, justifying-types, and the like. This type-mold is provided with a plurality of parallel cross-cavities in a plane, and consequently the type-ejecting device according to our invention comprises a comb-like ejector, the teeth of which are either made in one piece with a part of the machine or secured thereon by suitable known means. In the latter case the construction is such that the distances between the several teeth can be varied according to the circumstances.

The type-ejecting device also comprises a,

' comprises a shelved frame for receiving the types ejected from the type-mold, a second e ector for moving the ejected types off the shelves of the shelved frame; further, a plurality of conducting-channels, either inclined or horizontal, for receiving the types moved off, and a receptacle with a plurality of compartments for collecting the types falling from the conducting-channels.

We will now proceed to fully describe and explain our invention with reference to the accompanying drawings, in wl1ich Figure 1 is a plan of the type-mold for a type-casting machine and a block of matrices applied to the front of the type-mold. Fig. 2 is an elevation of the type-mold. Fig. 3 is a plan of the bottom part of the typemold. Fig. 4. is a cross-section through the line A B in Figs. 1 and 2. Fig. 5 shows, on an enlarged scale, a section through a part of the mold on the line C D in Fig. 2, the printing-surfaces on the front in Fig. 2 being turned upwardly. Fig. 6 shows in elevation, on areduced scale, the gear or mold wheel of a linotype casting and composing machine with a modified type-mold secured therein, also the frame for receiving the ejected cast types, a

second ejector for removing these types from the frame, the inclined conducting-channels, and the receptacle, the front wall covering the conducting-channels being removed to show thelatter. Fig. 7is partly a longitudinal section through the line E Fin Fig. 6 and shows part of the melting-pot and the gear-wheel, both partly in section; further, the frame, the cond noting-channels, and the receptacle. Fig. 8 is a horizontal section through the line G H in Fig. 6 and shows, on an enlarged scale, the lower part of the type-mold. Fig. 9 is a Vertical longitudinal section, on an enlarged scale, through the line I K in Fig. 6, the mold-wheel 14 having been turnedthrough an angle of two hundred and seventy degrees from its casting position shown. Fig. 10 is a horizontal section, on an enlarged scale, through a part of the type-mold in Fig. 2 on the line C D and shows a part of the ejector applied thereto. Fig. 11 is a side view of the guide for the ejector shown at Fig. 10. Fig. 12 is a cross-section through the line L M in Fig. 13, seen in the direction of the arrows. Fig. 13 is a section through a modified ejector on the line N O in Figs. 12 and 14. Fig. 14. is a side View of the guide therefor; and Fig. 15 is a view similar to Fig. 6, showing modified conducting-channels.

Similar characters of reference refer to similar parts throughout the several views.

'The type-mold described in our other application aforesaid as applied to a type-casting machine of any known construction is represented at Figs. 1 to 5. It is made in two parts 1 and 2, the lower part, 2, of which is provided with a plurality of partition-walls 3 3, so that a plurality of cells or cavities 4 4 is thereby formed in which the types 5 5 can be cast. The type-mold is secured either on a stationary part or on a moving part of the machine, as the case may befor example, by means of screws passing through the holes 7 7. Then a block of matrices 8 or a matrixblock secured between two vise-jaws 9 9 on a known moving or stationary part of the machine is applied to the front of the type-mold, and the mouthpiece 11, Fig. 4, of the meltingpot is applied to the rear side of the same, so that by means of a pump (not shown) the liquid metal can be forced from the melting-pot through the mouthpiece 11 into the cavities 4 4 of the type-mold to fill them out. The metal in these cavities having become torpid the type-mold is again released from the mat rices 8 8 or the matrix-block and the mouthpiece 11, and the feet of the cast types 5 5 are in the usual manner trimmed by a knife 12, Fig. 5. This knife 12 is either stationary, if the type-mold is moved aside by the respective machine part, or movable, if the typemold is stationary, in which case of course the mouthpiece will have to be moved off so much as to leave suflicient room for the trim ming-knife. Afterward the finished types 5 5 are ejected from the type-mold by a comblike ejector of either of the two constructions shown at Figs. 10 to 14. r

Fig. 10 shows a part of an ejector 24, which is actuated from the machine in any known and approved manner. It is made in one piece with a plurality of teeth 25 25 of rectangular cross-section, which latter are adapted to engage in the cavities 4 4 of the typemold. The free ends of these teeth 25 25 are guided in corresponding holes 26 26 of a guide 27. This guide may be secured either on a stationary part or on a moving part of the machine, according to the construction of the latter. If the type-mold is stationary, after the casting operation the mouthpiece 11 of the melting-pot is first moved from the rear side of the type-mold, then the trimming-knife 12 is moved to trim the feet of the cast types, and afterward the guide 27 and the ejector 24 are applied to the rear side of the typemold by means of suitable machine parts, so that the teeth 25 25 of the ejector and the holes 26 26 of the guide are exactly opposite to the rear ends of the cavities 4 4 of the typemold, as is shown at Fig. 10. Now by the respective machine part the ejector 24 is actuated to eject the finished types from the type-mold. If the type-mold is secured on a moving machine part, it will depend upon the construction of the machine whether the guide 27 be made stationary or secured on a moving machine part, and thereby applied to the rear side of the type-mold. of the partition-walls 3 3 of the type-mold are provided with projections or noses 6 6, as de-.

scribed in our other application for patent, to facilitate the trimming ofthe feet of the typebars it is evident that the cross-sections of the teeth 25 25 of the ejector will have to be reduced in proportion.

Figs. 12 to 14 represent a modified form of construction of the ejector. The teeth 28 28 are round rods, which are secured between the ejector 29 and a convenient plate 30 by means of bolts 31 or the like. The guide 32 is of course provided with a plurality of round holes 33 33. This construction affords the advantage that the distances of the several teeth 28 28 can be altered at pleasure to suit them to the cavities of other type-molds to be employed, in which case of course the guide 32 will have to be replaced. It is very easy to adjust the several teeth 28 28, as all that is required is merely to put the ends of the teeth into the holes 33 33 of the guide 32 and to secure their other ends between the ejector 29 and the plate.

In case the rear ends' When applying the type-mold to a linotype 4 casting and composing machine, it is suitably modified and secured in place of the linotypemold in the opening 13 of the rotating gear or mold wheel 14, Fig. 6, in the usual manner-for example, by means of set-screws 15 and screws 16. When the gear-wheel 14 occupies the position shown at Fig. 6, the rear ends of the cells or cavities 17 17, Fig. 8, in the mold 18 19 will be exactly opposite to the horizontal opening 20 of the mouthpiece 21 on the melting-pot 22. (See Fig. 7.)

At the front side of the gear-wheel 14 a vertical frame 341's secured on the machine-frame in any convenient manner, (not shown,) which is open on three sides and provided with a plurality of horizontal shelves 35 35 (Fig. 9) for receiving the ejected types. Obviously the shelves 35 35 require to be placed at the proper varying distance from each other according to the breadth of the respective types ejected. At the rear side of the gear-wheel 14 the ejector 36 is arranged, which is periodically moved from the machine to eject the cast types from the cavities 17 17. Of course its teeth 37 37 are each made of the width equal to that of the respective cell or cavity 17, (or reduced by that of the projection or nose similar to 6 6 in Fig. 5, if any are employed.) These teeth 37 37 are guided on their free ends in thesuitably-formed perforations of the guide 38, secured on the machine-frame.

The guide 38 is preferably so arranged that it can be replaced by another one. When the gear-wheel14 occupies the position for the ejection of the types, the teeth 37 37 of the ejector 36 can engage in the cells or cavities 17 17 of the mold, as is shown at Fig. 9.

second similarly-shaped ejector 39, made in one piece with a frame 40, (see Fig. 6,) is according to our invention disposed'onthe front side of the gear-Wheel 14. The right ends of the teeth of this ejector 39 are guided by thev shelves 35 35 of the .frame 34 and adapted to convenient manner. (Not shown.) The recep-v tacle 43 and the channels 41 41 are secured on the machine-frame in any approved manner.

This type-ejecting device is operated in the following manner: When during the operation of the machine the gear-wheel 14 occupies the casting position shown at Fig. 6 and the matrix-block 23 is pressed against the front of the mold 18 19, Fig. 7, by the respective machine part, the known pump will force the liquid metal out of the melting-pot 22 through the opening 20 of the mouthpiece 21 into the cavities 17 17 of the mold to fill them out.

manner rotated through three-fourths of a revolution, during which the feet of the types are trimmed by the known knife on the rear side of the gear-wheel. \lVhen the latter assumes the ejecting position, in which the cells or cavities 17 17 of the mold 18 19 are exactly opposed to the teeth 37 37 of. the ejector 36 on the rear side and to the shelves 35 35 of the frame 34 on the front side, Fig. 9, the ejector 36 is actuated in the known manner for simultaneously ejecting all the types from the mold on the shelves .35 35. Thereupon. the second ejector 39 is actuated to throw the types off the shelves 35 35, so that theycslide down the channels 41 41 into the compartments 42 42 of the receptacle.

The two ejectors 36 and 39 may also be constructed'in the manner shown at Figs. 12 to 14. The cross-section of the teeth 25 25 or 28 28 or 37 37 may be of any other shape. The construction of the ejector with detachable and adjustable teeth may be varied according to the circumstances.

In case the type-mold is applied to a typecasting machine the type-ejecting device may also comprise a shelf or a shelved frame for.

receiving. the ejected types, further conducting-channels, and a receptacle similar to those described above. A second ejector may in this case be omitted. I

The whole type ejecting device can be varied in many respects without deviating from the spirit of our invention.

Instead of the inclined channels 41 41 (shown at Fig. 6) horizontal channels 45 45, with vertical channels 46 46, (see Fig. 15,) may be employed, in which case the teeth 37 37 (or 28 28) of the second ejector 36 (or 29) push the Thereupon the matrix-block 23 is re: moved, and the gear-wheel 14 is in the usual ejected types forward until they drop into the respective compartments 42 42 of the receptacle 43.
